RAILWAY-FROG- Specification of Letters Patent.

Patented Nov. 6, 1906.

Application filed June 29,1906. Seria1No.324.09o.

To all whom it may concern:

Be it known that I, CARL F. BOYENS, a citizen of the United States, residing at Allentown, in the county of Lehigh and State of Pennsylvania, have invented certain new and useful Improvements in Railway-Frogs, of which the following is a specification.

My invention pertains to improvements in railway-frogs. Its object is to permit of a yielding or spring action of a wing-rail at the juncture of the frog-point, forming rails therewith as the wheels pass over the same in crossing from one track to another; to guard against derailment at this oint in event of breaking of said movable rai to provide for the effective retention and bracing of the rails in place upon a base-plate; to prevent the upward (llSHllCGHlGIlt of the movable wing-rail, as we as of the adjunctive means permitting of the yielding action of the movable wingrail; to control or limit the lateral or sliding movement of the movable part, and to carr out these ends in a simple, durable, and e fective manner.

Said invention consists of certain features substantially as hereinafter disclosed, and specifically pointed out by the claims.

In the accom anying drawings, illustrating the preferre embodiment of my invention, Figure 1 is a plan view thereof. Fig. 2 is a cross-section o the same produced in the line of the spring controlling the movablewin -rail. Fig. 3 is a like section taken in the ine of one of the rail retaining and bracing cli s or fastenings upon one side of the movab e wing-rail and a clip upon the opposite side of the opposite wing-rail. Fig. 4 is also a like view produced through a filling-in iece or member at the bifurcation of the og. Fig. 5 is a horizontal section taken principall through the rail securing or retaining c ips or fastenings or adjunctive arts. p In the disclosure of my invention I rovide a foundation or base late 1, suitab y fixed in position upon embedded transverse pieces, all arranged in a plane below the tracks. Upon this foundation or base plate 1 are arranged or supported the wing-rails 2 3 and the frog-point-forming portions of the rails 4 4 of the tracks, all generally assembled in the usual way. The wing-rail 2 is fixed, being held in place by the approximately rightangled clips or fastenings 2, having their vertical portions bolted to the web of the rail and their horizontal portions bolted to the foundation-plate 1 and recessed in their lower surfaces, as at 6, to receive and conform to the rail flange or base, the same having their upper surfaces corres ondingly upraised or thickened, as at 7, t e purpose of which is obvious. The op osite or movable wing-rail 3, suitabl or yie dingly connected by a nut-equippe bolt 8 to the aforesaid fixed wing-rail, as bolted to its web portion the upper plate-terminated ends of practically ri ht-angled clips or fastenings 9, whose verticaI portions are each of a greater general cross-section than the horizontal arms thereof and have opposite lateral recesses or grooves 10, which receive the corresponding edges of slots 11, produced in the base or foundation plate 1. The effect of this arrangement is to form a slidable or movable connection between this latter wing-rail and the foundation or base late 1, the purpose of which will be presently apparent.

A somewhat tapered sleeve or cufi 12, having also an upward and inward extended plate-terminated arm 13 passing through slots 14 in the foundation or base plate 1 and bolted to the web of the movable rail, is arranged underneath or below the foundationplate 1, and through this sleeve or cuff passes a rod 15, having one end also secured to the under side of said plate. Upon this rod 15 is arranged a preferably coiled or helical spring 16, with one end seated in and delivering its pressure upon said sleeve or cufi 12 and having its opposite end held in place upon said rod by a nut 17, and this locked from reversely turning by a jam or look nut 18, both said nuts being screwed-upon said rod. B this arrangement it will be noted that as t e wheel-flange engages the movable wing-rail the latter will yield laterally or horizontally and accordingly after the passage of the wheel or wheels be automaticall restored to its initial position in contact with the pointed rails by the recoil action of the spring 16 which had become compressed b such engagement of the wheel-flange with said wing-rail. The several slots 11 14 have secured across them at predetermined points for requisitely limiting or restricting the movement of the several cli s 9 and the cufi.

12 plates 19, suitably bolte to the foundation or base plate 1, as disclosed particularly in the plan view. It is also noted that the clips 9 and cuff 12 have the efiect to prevent the upward dis lacement of the movable wing-rail, as wel as topermit of the sliding ICC i movement of the latter, as it is subjected to 'or blocks are suitably secured in place to said rails by means of nut-equipped bolts 22 23', respectively, passing therethrou'gh, as indicated.

Steel or metal plates 23' are suitably applied and bolted to the movable wing-rail 3' along its web portion to provide, should the railbecome'broken, against the displacement of the thus dismembered parts thereof, andthus prove efiective against accidental derailment of the rolling-stock."

I claim' 1. A device of the character described,

comprising a movable wing-rail, a base or foundation plate for the support of said wingrail and clips secured to said rail and having lateral recesses or grooves in their vertical portions which recesses or grooves receive the lateral edges of slots in said base or foundation plate.

2. A device of the character described, comprising wing-rails opposed to the frogpoint-forming rails, a base-plate for the sup port of said rails, and clips, one set being right-angled in outline and adapted to con.- form to the flange of one of said rails and secured to the webthereof and to said plate, and the other set of said clips having their vertical portions provided with lateral or horizontal slots receiving the edges of slots in said plate.

In testimony whereof I have signed my name to this specification in the presence of twosubscribing Witnesses.

CARL F. BOYENS.
